Malone Family from Tullamore

This may well be a long-shot, but I’m looking for any information pertaining to the Joseph and Katie (Kelly) Malone family who lived in Tullamore, Co. Offaly in 1900’s, at least until the 1950s/1960s.

Joseph and Katie were my Great Grandparents, and their son, William Patrick (“Pat”) was my Grandfather. Pat was born in 1906 and left Tullamore, with his brother John, for America in 1923.

Pat had 3 half-siblings, Edward, James and John Malone. To my knowledge, both Edward and James remained in Ireland.

Pat also had 4 siblings, Julia, Catherine, Joseph and Mary. Julia emigrated to America but, to my  knowledge, Catherine, Joseph and Mary remained in Ireland.

Any information is appreciated!
